Citric Acid Cycle

This animation shows the reactions of the citric acid cycle, which splits off carbon atoms and generates energy-rich reduced forms of cofactor molecules. It is the first of three animations about cellular respiration.

ATP Synthesis

This animation shows how the proton gradient across the mitochondrial membrane powers the ATP synthase enzyme to make ATP. It is the third of three animations about cellular respiration.

Electron Transport Chain

This animation shows how the enzyme complexes of the electron transport chain harvest energy from cofactor molecules to pump protons across the mitochondrial membrane and establish a chemical gradient. It is the second of three animations about cellular respiration.

The Science of an Extreme Animal Athlete

This video follows biologist Shane Campbell-Staton, who is studying the adaptations that allow deer mice living at high elevations to stay warm and active during the winter.

Photosynthesis

This multipart animation series explores the process of photosynthesis and the structures that carry it out.

Animated Life: Pangea

This animated short video celebrates the early 20th-century German astronomer and atmospheric scientist Alfred Wegener, who first proposed that continents once formed a single landmass and had drifted apart.

Coral Bleaching

This animation zooms into a coral reef to explore the tiny animals that build reefs, the photosynthetic algae inside their cells, and the damaging process of coral bleaching.

The Day the Mesozoic Died

This film tells the story of the scientific quest to explain one of the greatest, long-standing scientific mysteries: the sudden disappearance of the dinosaurs at the end of the Cretaceous period.

How To Find a Dinosaur

In this video, Tyler Lyson describes and demonstrates how he and other paleontologists uncover fossils from prehistoric animals, including dinosaurs.

Stratigraphic Principles

This video provides a demonstration of two main principles in the study of rock layers: superposition and association.
